Answer:
Helmets-12
Baseballs-32
Step-by-step explanation:
Given the tax rate as 6% and the reduced prices as $2.25/baseball and $22.50/helmet and that the budget is $400:
The new prices are reduced price plus tax:
Let x be the number of groups of 8 baseballs as well as the number of groups of 3 helmets,therefore:
Substitute for x=4 to find the highest number of baseballs and helmets:
Helmets=4x3=12
Baseball=4x8=32
#Price cost will be 12x23.85+32x2.39=362.68 (balance=37.32)
Hence, Shaw can buy 12 helmets and 32 baseballs and still remain with $37.32

Answer:
25 liters of the 16% solution should be added.
Step-by-step explanation:
pure acid amount + pure acid amount = total pure acid amount
0.02*10 + 0.16*x = 0.12*(10+x) <<<---=== it is your balance equation; x is the amount (in liters) of the 16% solution.
0.02*10 + 0.16x = 0.12*10 + 0.12*x
0.16*x - 0.12*x = 0.12*10 - 0.02*10
(0.16 - 0.12)*x = 0.12*10 - 0.02*10
x = %280.12%2A10-0.02%2A10%29%2F%280.16-0.12%29 = 25.
Answer. 25 liters of the 16% solution should be added.
Check. %280.02%2A10+%2B+0.16%2A25%29%2F%2810+%2B+25%29 = 0.12 = 12% of concentration of the final mixture. ! Correct !
